2 Claims. (Cl. 242-58) This invention relates to apparatus for handling filaments, and more particularly to web-supplying devices.

In manufacturing operations wherein paper or other webs are supplied to a processing or other type of apparatus from heavy supplying rolls, it has been difficult to load such supply rolls into supply stands. This difficulty is very pronounced where the supply stand is enclosed within a housing or the like, and the supply roll must be lifted onto the supply stand. No supply stands facilitating such loading operations have been available in the past.

An object of the invention is to provide new and improved apparatus for handling filaments.

A further object of the invention is to provide new and improved supply stands.

Another object of the invention is to provide supply stands and loading devices therefor, whereby heavy rolls of webbing, such as paper or the like, may be easily loaded into supplying position on the supply stands even though the supply stands are enclosed within housings.

An apparatus illustrating certain features of the invention may include a pair of guide racks for receiving the arbor supporting a supply roll, a pair of arbor sup porting bearings positioned at the end of the guideways and a pair of guideway extensions mounted at the other ends of the guideways pivotally between positions in alignment with the guideways and positions folded back on the guideways.

A complete understanding of the invention may be obtained from the following detailed description of an apparatus forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which Fig. 1 is a front, elevation of an apparatus forming one embodiment of the invention;

Fig. 2 is a fragmentary, vertical section taken along line 22 of Fig. 1;

Fig. 3 is a top plan view of an apparatus shown in Fig. 1 with the elements thereof in certain positions, and

Fig. 4 is a fragmentary, top plan view similar to Fig. 3 with the elements of the apparatus shown in different positions from the positions in which they are shown in Fig. 3.

Referring now in detail to the drawings, there is shown therein a supply stand 11 for supporting a roll of webbing, such as for example, paper or the like. This apparatus includes racks 12 supported by tracks 14 fastened to braces 13 pivotally to a housing 15 by pins 16 and brackets 17. The inner ends of the tracks 14 are pivoted on shoulders 19 on tracks 20 by pins 21 located directly above the pins 16. Latching pins 22 are designed to enter holes 23 formed in the shoulders 19 to hold the tracks 14 in positions extending from the tracks 20 and the racks 12 extending from racks 25 fixed to the tracks 20.

Cones 27 mounted removably on a shaft 18 support the roll 10. Pinions 30 detachably fixed to the shaft 18 mesh with the racks 12 and 25 to prevent cocking of the shaft. The pinions 30 may be rolled along the racks 12 and 25 to locate the ends of the shaft 18 over upwardly facing bearings 31, and the ends of the shaft 18 drop into these hearings, which support the roll rotatably so that the paper may be withdrawn from the roll. The racks 12 form diagonal junctions with the racks 25 so that gaps therebetween are prevented. The tracks 14 are provided with stops at the ends thereof, which prevent the shaft 18 from rolling off the tracks 14. The

ice

Operation The tracks 14 and the racks 12 are swung to the positions in which they extend from the tracks 20 and the racks 25, and are latched by the pins 22 in these positions, in which positions the racks 12 and the tracks 14 extened substantially beyond the housing 15. The supply roll mounted on the shaft 18 is lifted over the stops 35 and is lowered to a position in which the pinions 30 mesh with the racks 12, and the shaft extends transversely to the racks 12 and is supported by the tracks 14. The roll 10 is rolled onto the housing, the pinions 30 rolling along the racks 12 and 25, and the ends of the shaft 18 roll along the tracks 14 and 20 and drop into the bearings 31, which support the shaft rotatably therein. The pins 22 then are actuated to release the racks 14 and the tracks are folded back into the housing 15 so that clearance in the space normally occupied is provided and the opening in the housing may be covered if desired.

The above-described apparatus may be easily loaded and may be completely enclosed within the housing during the paying out of the paper from the supply roll, and is simply and strongly constructed while inexpensive to build and maintain.

It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of the invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.

What is claimed is:

1. A supply stand, which comprises a housing having an opening in a wall thereof and closed walls on opposite sides of the opening, tracks mounted substantially horizontally on said opposed walls in parallel positions, half bearings mounted at the inner ends of the tracks for mounting an arbor, racks fixed to the tops of the tracks in upwardly facing positions, said tracks extending along inside edges of the racks, angular arms mounted pivotally on the housing at the opening and movable between positions extending out of the opening in the housing and positions folded within the housing, track extensions mounted on the arms in positions extending therealong, rack extensions mounted on the arms in positions extending along the track extensions thereon, and an arbor provided with pinions keyed to the end portions thereof for meshing with the racks and rack extensions resting on the tracks and track extensions, said racks and rack extensions and pinions serving to prevent cocking of the arbor with respect to the tracks and track extensions as the arbor is rolled along the tracks and the track extensions.

2. A supply stand, which comprises a housing having an opening in a side thereof and walls on opposite sides of the opening, a pair of guide rails mounted horizontally on said opposed walls in parallel positions extending from the opening on into the housing, a pair of racks fixed to the rails, half bearings mounted at the inner ends of the rails for mounting an arbor rotatably, a second pair of guide rails mounted pivotally on the outer ends of the first-mentioned rails and movable between positions extending out of the opening in the housing from the first-mentioned rails and portions folded into the housing, a second pair of racks mounted on the second pair of rails, an arbor provided with pinions keyed to the end portions thereof for meshing with the pairs of racks, said arbor being designed to roll on the rails, a pair of brackets supported by the housing in positions at and below the outer ends of the first pair of guide rails, and a pair of braces mounted pivotally on the brackets and secured to the second pair of guide rails for supporting the outer ends of the second pair of guide rails.
